The v-y latissimus dorsi musculocutaneous flap in the reconstruction of large posterior chest wall defects.

Posterior chest wall defects are frequently encountered after excision of tumors as a result of trauma or in the setting of wound dehiscence after spine surgery. Various pedicled fasciocutaneous and musculocutaneous flaps have been described for the coverage of these wounds. The advent of perforator flaps has allowed the preservation of muscle function but their bulk is limited. Musculocutaneous flaps remain widely employed. The trapezius and the latissimus dorsi (LD) flaps have been used extensively for upper and middle posterior chest wounds, respectively. Their bulk allows for obliteration of the dead space in deep wounds. The average width of the LD skin paddle is limited to 10-12 cm if closure of the donor site is expected without skin grafting. In 2001 a modification of the skin paddle design was introduced in order to allow large flaps to be raised without requiring grafts or flaps for donor site closure. This V-Y pattern allows coverage of large anterior chest defects after mastectomy. We have modified this flap to allow its use for posterior chest wall defects. We describe the flap design, its indications, and its limitations with three clinical cases. Level of Evidence V This journal requires that authors assign a level of evidence to each article.

High-resolution selective three-dimensional magnetic resonance coronary angiography with navigator-echo technique: segment-by-segment evaluation of coronary artery stenosis.

PURPOSE: To investigate the feasibility of high-resolution selective three-dimensional (3D) magnetic resonance coronary angiography (MRCA) in the evaluation of coronary artery stenoses. MATERIALS AND METHODS: In 12 patients with coronary artery stenoses, MRCA of the coronary artery groups, including the coronary segments with stenoses of 50% or greater based on conventional x-ray coronary angiography (CAG), was performed with double-oblique imaging planes by orienting the 3D slab along the major axis of each right coronary artery-left circumflex artery (RCA-LCX) group and each left main trunk-left anterior descending artery (LMT-LAD) group. Ten RCA-LCX and five LMT-LAD MR angiograms were obtained, and the results were compared with those of conventional x-ray angiography. RESULTS: Among 70 coronary artery segments expected to be covered, a total of 49 (70%) segments were fully demonstrated in diagnostic quality. The identification of segmental location of stenoses showed as high an accuracy as 96%. The retrospective analysis for stenosis of 50% or greater yielded the sensitivity, specificity, and accuracy of 80%, 85%, and 84%, respectively. CONCLUSION: Selective 3D MRCA has the potential for segment-by-segment evaluation of major portions of the right and left coronary arteries with high accuracy.

Epidemiological and immunological aspects of human visceral leishmaniasis on Margarita Island, Venezuela

Sixty-five patients were diagnosed with visceral leishmaniasis (VL) on Margarita Island in the decade from 1990 to1999; 86.2% were <= 3 years old. All were leishmanin-negative at diagnosis. Evaluation of 23 cured patients in 1999 revealed that 22/23 had converted to leishmanin-positive; five had persisting antibodies to rK39 antigen, with no clinical evidence of disease. Leishmanin tests were positive in 20.2% of 1,643 healthy individuals from 417 households in endemic areas. Of the positive reactors, 39.8% were identified in 35 (8.4%) of the households, 15 of which had an antecedent case of VL, a serologically positive dog or both. Weak serological activity to rK39 antigen was detected in 3 of 488 human sera from the endemic areas. The presence of micro-foci of intense peri-urban transmission and the apparent absence of other Trypanosomatidae causing human disease offer a unique opportunity for the study of reservoirs, alternative vectors and evaluation of control measures on the Island.

Troubles cognitifs séquellaires de la rupture d'anévrysmes de l'artère communicante antérieure et de l'artère cérébrale antérieure. Etude rétrospective de 56 cas [Cognitive sequelae following rupture of aneurysms of the anterior communicating artery and the anterior cerebral artery. Retrospective study of 56 cases].

The neuropsychological records of 56 patients operated for clipping were studied. Almost every patient remained autonomous and without invalidating motor defect. The present study was aimed at specifying the type and frequency of neuropsychological sequelae and, to a lesser extent, the role of various pathophysiological factors. A main concern was to examine to what extent and at what post-operative interval the neuropsychological assessment can predict the intellectual and socioprofessional outcome of each individual patient. The neuropsychological assessment performed beyond the acute phase showed evidence of intellectual sequelae in about two thirds of the patients. Only one case of permanent anterograde amnesia was observed, probably due to unavoidable inclusion of a hypothalamic artery in the clip during surgery. Transient anterograde amnesia and confabulations were occasionally observed, generally for less than three weeks. A common finding was impaired performance on memory and/or executive tests. In a minority of patients, language disorders, visuoperceptive and visuoconstructive disabilities were found, probably in relation with hemodynamic changes at distance from the aneurysm. Global impairment of intellectual function was not uncommon in the acute post-operative phase but it evolved in most cases towards a more selective impairment, for instance restricted to executive and memory functions, in the chronic phase. The neuropsychological investigation carried out 4 to 15 weeks post-operatively provided satisfactory information about possible long-lasting intellectual disturbances and professional resumption. In particular, persistent global intellectual impairment, persistent amnesia and confabulations 4-15 weeks post-operative were associated with cessation of professional activity; executive and memory impairment, behavioral disturbances such as those encountered in patients with frontal lobe damage were associated with a decreased probability of full-time employment. Pre- and post-operative angiography were not good predictors of long-term cognitive outcome: normal angiography was not necessarily followed by normal neuropsychological outcome, conversely abnormal angiography could be found together with normal neuropsychological outcome. By contrast, there was a relationship between left-lateralised abnormalities on post-operative angiography and occurrence of language disorders; similarly, there was a relationship between side of craniotomy and type of deficits, that is language disorders versus visuoperceptive-visuoconstructive impairments.

Lack of association between connexin40 polymorphisms and coronary artery disease.

OBJECTIVE: Cx40 is a gap junction protein important for cell-cell communication in the endothelium. Polymorphisms in the promoter region of the human Cx40 gene, -44G>A and +71A>G, were shown to reduce Cx40 transcription by half. As mice with an endothelial-specific deletion of Cx40 are more susceptible to atherosclerosis, this study was designed to discover a correlation between these polymorphisms and atherosclerosis in European populations.¦METHODS AND RESULTS: 803 patients referred to the Geneva University Hospitals for elective coronary angiography were divided according to the number of significantly stenosed vessels (from 0 to 3) and were genotyped for the Cx40 polymorphisms. Genotype distribution in the control group was -44GG/+71AA=59.8%, -44AG/+71AG=35.1% and -44AA/+71GG=5.2%. Surprisingly, this distribution was similar in the CAD group, with -44GG/+71AA=58.5%, -44AG/+71AG=37.6% and -44AA/+71GG=3.8% (p=0.67). Moreover, no significant association between histological carotid plaque composition of culprit lesions and Cx40 polymorphisms could be detected in 583 Dutch patients of the Athero-Express study.¦CONCLUSIONS: Despite a clear antiatherogenic role of Cx40 in mice, our study could not detect an association of Cx40 promoter polymorphisms and CAD in human. Moreover, a correlation with atherosclerotic plaque stability or hypertension could not be demonstrated either. Connexin polymorphisms affecting channel function may be of greater importance for cardiovascular disease than polymorphisms affecting the expression level of the protein.

Atrial fibrillation and minimally invasive coronary artery bypass grafting: risk factor analysis.

Atrial fibrillation (AF) is a frequent arrhythmia after conventional coronary artery bypass grafting. With the advent of minimally invasive technique for left internal mammary artery-left anterior descending coronary artery (LIMA-LAD) grafting, we analyzed the incidence and the risk factors of postoperative AF in this patient population. This prospective study involves all patients undergoing isolated LIMA-LAD grafting with minimally invasive technique between January 1994 and June 2000. Twenty-four possible risk factors for postoperative AF were entered into univariate and multivariate logistic regression analyses. Postoperative AF occurred in 21 of the 90 patients (23.3%) analyzed. Double- or triple-vessel disease was present in 12/90 patients (13.3%). On univariate analysis, right coronary artery disease (p <0.01), age (p = 0.01), and diabetes (p = 0.04) were found to be risk factors for AF. On multivariate analysis, right coronary artery disease was identified as the sole significant risk factor (p = 0.02). In this patient population, the incidence of AF after minimally invasive coronary artery bypass is in the range of that reported for conventional coronary artery bypass grafting. Right coronary artery disease was found to be an independent predictor, and this may be related to the fact that in this patient population the diseased right coronary artery was not revascularized at the time of the surgical procedure. For the same reason, this risk factor may find a broader application to noncardiac thoracic surgery.

ASIST suicide prevention training - all-island evaluation report

The findings of a Public Health Agency evaluation report on a suicide prevention training programme were today presented at the North South Ministerial Council Health Sector meeting.ASIST, The Applied Suicide Intervention Skills Training programme, has to date been delivered to more than 20,000 people in the Republic of Ireland and more than 11,000 people in Northern Ireland. This two day course, delivered by a wide range of organisations including those from the voluntary/community sector, for professionals and the public helps individuals provide emergency help to people at risk of suicidal behaviour. It also develops a cooperative network among participants, since often many people have to work together to prevent suicide.Talking about the findings of this work, Dr Eddie Rooney, Chief Executive, PHA, said: "Both the PHA and the National Office for Suicide Prevention (NOSP), based in the Republic of Ireland, are concerned for any loss of life through suicide and we send our condolences to all families who have been bereaved. We know ASIST training brings a positive element to suicide prevention. Those who have been trained said that the two biggest advantages are that they know when, how and have the confidence to help people who are under pressure and that it helps to build positive links between community and voluntary organisations and the health service. I am pleased that this has been borne out in the evaluation and we hope ASIST will continue to be of enormous benefit and will contribute to a reduction in suicidal behaviour and the tragedy that this brings to our community".This evaluation found that within organisations where staff had participated in ASIST training, there were improvements in service development; staff attitudes, confidence and skills in relation to suicide and suicide intervention and in policies and procedures. At a community level, ASIST was found to have contributed to a sense of empowerment through an increased confidence in being able to deal with suicide and suicidal behaviour.The report also shows that the ASIST model offers a common language, helping communication between the community or voluntary organisations and those from a health background. In fact this training helped to cancel out any differences between those with mental health qualifications and those without, in terms of knowledge, skills, attitude and willingness to intervene. The study also confirmed that ASIST training was most relevant to those who were likely to be in contact with a person 'at risk'.In welcoming the publication of the report Geoff Day, Director of the NOSP, said: "This report is an independent evaluation of the ASIST programme, it has allowed us to demonstrate the effectiveness of the programme in increasing community participants confidence and ability to respond to individuals in suicidal crisis.He added: "The fact the evaluation was completed on an all-island basis allows the NOSP and the PHA to avoid duplication of resources, improve coordination of suicide prevention training programmes across both jurisdictions and allows us to learn from different approaches used in suicide prevention across the island of Ireland."He reiterated the Health Service Executive commitment to the continued implementation of quality assured training programmes as part of Reach out: the National Strategy for Action on Suicide Prevention.ASIST training is being rolled out in Northern Ireland as part of the implementation of the 'Protect Life' suicide prevention strategy, which was published by the Department of Health, Social Services and Public Safety in 2006.A copy of the evaluation report can be found below and in the publications section of this website, by clicking here

Salmonella in pork on the island of Ireland

A study was carried out on the occurrence of Salmonella on pork on the island of Ireland and an assessment of the risk factors contributing to its transmission. It included microbiological studies to track the Salmonella status of individual pigs through the pork chain from farm to primal cuts. Studies on the Salmonella status of pork cuts in boning hall, and on raw pork cuts at retail were also undertaken. A quantitative microbial risk assessment model was developed for Salmonella on pork cuts covering the chain from slaughter to boned-out cuts.

The Economic Impact of Gastroenteritis on the island of Ireland

The main objective of this study was to estimate the economic burden of gastroenteritis on the island of Ireland.

A Study of Food Safety Knowledge, Microbiology and Refrigeration Temperatures in Restaurant Kitchens on the Island of Ireland

A population-based telephone survey conducted in 2002 estimated that there were 3.2 million episodes of acute gastroenteritis on the island of Ireland each year (Scallon et al., 2004). It is often very dif ficult to definitively identify the source of illness. However, of the respondents in that study suspecting food as the reason for their illness, 74% blamed food consumed from commercial premises such as restaurants, cafés, takeaways, canteens and pubs. Within the food services industry, statistics show a significant level of prosecutions, prohibition and closure orders of restaurants for food hygiene offences. The Food Safety Authority of Ireland has identified the main contributory factors to foodborne infections to be: cross-contamination, inadequate cooking, inadequate storage, inadequate reheating, delayed serving and infected food handlers (FSAI, 2000). Development of appropriate training and education campaigns to target problem areas requires initial understanding of the current level of food safety knowledge and practices in the food services industry.
